Security checks for vulnerabilities and agentic risk

Overview

This is a simple note-taking skill, but users should be aware that it describes storing, syncing, and sharing note content through an unspecified backend.

Only store or share notes you are comfortable sending to the skill's unspecified backend. Look for provider details, privacy terms, and confirmation behavior before using it for sensitive personal, business, or regulated information.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The invocation description is broad enough to capture many generic note-related requests without clearly defining operational boundaries. Overly broad routing can cause the skill to activate unexpectedly, increasing the chance that user data is handled by this skill when the user did not intend it, especially given the skill also advertises syncing and sharing behavior.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill promotes syncing notes across devices and sharing notes with other users but provides no warning about privacy, data disclosure, or where note content is stored and transmitted. Because notes often contain sensitive personal or business information, missing disclosure and consent language increases the risk of unintended exposure or transfer of sensitive data.
